Patented July 26, 1932 UNIT@ STATES PATENT OFFICE JOSEPH LEVY, orBnooxLINE, 'MASSACHUSETTS STAMP Application :tiled `September 29, 1936.Serial No. 485,092.

This invention relates to an improved hand stamp of the class in which aplurality of endless 'bands' are provided upon their surface' withcharacters such as numerals or letters. These endless bands aresupported at j voneend thereof upon` a plurality of pulleys. At theother end-they pass over a guide which in the present instancey forms across-bar of the the pulleys are mounted.

VIn order to position dierent numerals along the stamping line, or lineof Contact of the characters, with the surface which is to be printed,the bands are moved longitudinally dierent positions relatively toHeretofore this has been rendered very difficult by reason of the factthat when one band is moved the band adjacent thereto has been Vmovedwith it. In the hand stamp of this invention'novel means $0 are providedto overcome this diiculty, consisting of flanges of different diameterswhich are provided on the band pulleys, so that one pulley can berotated without rotat- .ing another pulley adjacent to it, and thus 25`each band may be eiciently and quickly positioned as may be desired, topresent the desired character at the contacting line.

The invention consists primarily in providing the band pulleys of ahand' stamp of l0' the character set forth with flanges of differentdiameters.

The invention further consists in certain details of construction ashereinafter def. scribed and pointed out in the claims. 5 Further, theinvention consists in a stamp embodying the combination of elements setforth in the following specification and particularly pointed out in theclaims.

Referring to the drawing:

0' Fig. 1 is a front elevation of the hand stamp of my invention.

Fig. 2 is a side elevation of the same. Fig. 3 is a. sectional elevationtaken on line 3-3, Fig. 1.

Fig. 4 is a detail side elevation of one of the band pulleys.

Fig. 5 is a detail transverse section of the band guide.

Like numerals refer to like parts through- 'o out the several views ofthe drawing.

In the drawing, 6 is a frame comprising a pair ofside members 7 and 8and a pair of cross bars 9 and 10. They side members 7 and and 8 projectinto grooves 11 formed in the guide cross-bar 10 and are rivetedthereto. i

A pin 12 extends across the frame 6 and through the two side members 7and 8 thereof and is fastened thereto. Upon this pin are mounted fourpulleys 13, 14, 15 and 16. Thesefour pulleys form a' series of pulleysyadjacent to each other and are rotatablyl mounted upon the pin 12. Thepulleys v13v and 16 form the terminal pulleys of the series and thepulleys 14 and 15 constitute the'r4 intermediate pulleys ofl theseries.- rlhe pulleys 13, 14, 15 and 16 are provided respec-l.. tivelywith flanges 17 18, 19 and 20. .The flanges 18 and 19 are of greaterdiameter than the flanges 17 and 20. A discf21 is mounted upon the pin12 between the pulleys 14 and'- 15. Endless bands 22, 23, 24 and 25 aremounted-.on the pulleys 13, 14, 15'and'16 respectively. Thesel bands areprovided re spectively with a series of Vnumerals 26, 27,1y

28 and 29, and thebands extend from `the pulleys around the band guideor cross-bar 10 W ich is provided withrounded corners 30. The cross-bar10 is also provided in its lower edgewith a recessed portion 33 which1...;

A detail front elevation ofthe pulley 16 is i j illustra-ted in Fig. 4as viewedv from the left;

of Fig. 3, and itwill be noted that the flange'l l2O of said pulley 16is provided with corrugav tions31 on itsinner face or on the face adjaecent to the pulley 16. The flange17-of the pulley 13 is also `corrugatedin like manner` onthe'face ladjacent to the pulley 13, while the flanges18 and 19 respectively .have the faces adjacent to the pulleys 14 and 15cor rugated. The object of these corrugations is to prevent the' bandsfrom slipping relafy tively to the pulleys when the pulleys are ziorotated by means of their respectiveV flanges. The pulleys-14 and 15 areseparated one from another by the disc 21 which projects outwardlybetween the bands 27 and 28, so that when these bands are adjusted onewill not move the other by frictional contact therewith.

In order to operate the stamp convenient? ly, a handle 32 is'providedwhich'is` fastened* tothe cross bar 9 of the frame. 1

The operation of the vdevice hereinbeforespecifically described is asfollows Assuming the different bands to be in the relativer.'

positions illustrated in the drawing and that it is desired to positionadifferent' `numeral. or numerals upon thecontacting line A-A, Fig. 2,if the numerals whichr it is intended to change is one of the numerals26, then the pulley 13 is rotated by means of the flange 'I7 and as thispulley is one 'of' the terminal pulleys and is positioned outside thepulley 14 VA6e adjacent thereto and has a flange 17 smaller in diameterthan the flange 18 on the pulley 14,it follows that the pulley 13 can beeasilyv rotated without disturbing the pulley 1145 until Ethe desirednumeral 26`is brought to the Contact line A-A- If itis desired to bringone of the numerals in the series v27 to the Contact line A-A,vthis isaccomplished byl rotating the pulley 14 by means ofthe flange 18 and asthe flange 18 is of greater diameter than the flange`17, said. flange 17will not be interfered with when the fiangelS is rotated by the lingersof the hand.4 The same ifs vtrue in relation to the setting of the bandwith the series 28 thereon, in which case the pulley 15 is rotated bymeans of the liange 191 and in the case Vof setting the numerals oftheband 25 the pulley 16 is rotated by means of its flange 20. Thus anyone'of the pulleys may be rotated and the band moved to bring anydesired numeral or upon its surface into the contact line without'vinterfering with the pulley and band or` bands adjacent thereto. Thestamp is used in the usual. manner, being manipulated by means of thehandle 32, and in the presentl instancey the bands and 'the charactersthereon are preferably composed of rubber.Y
